Evidence that immigrants tend to be underserved by the health-care system in the hosting country is well documented. While the impacts of im/migration on health-care utilisation patterns have been addressed to some extent in the existing literature, the conventional approach tends to homogenise the experience of racialised and White immigrants, and the intersecting power axes of racialisation, immigration and old age have been largely overlooked. This paper aims to consolidate three macro theories of health/behaviours, including Bronfenbrenner's ecological theory, the World Health Organization's paradigm of social determinants of health and Andersen's Behavioral Model of Health Service Use, to develop and validate an integrated multilevel framework of health-care access tailored for racialised older immigrants. Guided by this framework, a narrative review of 35 Canadian studies was conducted. Findings reveal that racial minority immigrants’ vulnerability in accessing health services are intrinsically linked to a complex interplay between racial-nativity status with numerous markers of power differences. These multilevel parameters range from socio-economic challenges, cross-cultural differences, labour and capital adequacy in the health sector, organisational accessibility and sensitivity, inter-sectoral policies, to societal values and ideology as forms of oppression. This review suggests that, counteracting a prevailing discourse of personal and cultural barriers to care, the multilevel framework is useful to inform upstream structural solutions to address power imbalances and to empower racialised immigrants in later life.

Background: Little is known about depression in middle-aged and older Canadians and how it is affected by health determinants, particularly immigrant status. This study examined depression and socio-economic, health, immigration and nutrition-related factors in older adults. Methods: Using weighted comprehensive cohort data from the baseline Canadian Longitudinal Study on Aging (n = 27,162) of adults aged 45–85, gender-specific binary logistic regression was conducted with the cross-sectional data using the following variables: 1) Depression (outcome) measured using the Center for Epidemiologic Studies Short Depression (CESD-10) rating scale; 2) Immigration status: native-born, recent and mid-term (< 20 years), and long-term immigrants (≥20 years); and 3) covariates: socioeconomic status, physical health (e.g., multi-morbidity), health behavior (e.g., substance use), over-nutrition (e.g., anthropometrics), under-nutrition (e.g., nutrition risk), and dietary intake. Results: The sample respondents were mainly Canadian-born (82.6%), women (50.6%), 56–65 years (58.9%), earning between C$50,000–99,999 (33.2%), and in a relationship (69.4%). When compared to Canadian-born residents, recent, mid-term (< 20 years), and longer-term (≥ 20 years) immigrant women were more likely to report depression and this relationship was robust to adjustments for 32 covariates (adjusted ORs = 1.19, 2.54, respectively, p < 0.001). For women, not completing secondary school (OR = 1.23, p < 0.05), stage 1 hypertension (OR = 1.31, p < 0.001), chronic pain (OR = 1.79, p < 0.001), low fruit/vegetable intakes (OR = 1.33, p < 0.05), and fruit juice (OR = 1.80, p < 0.001), chocolate (ORs = 1.15–1.66, p’s < 0.05), or salty snack (OR = 1.19, p < 0.05) consumption were associated with depression. For all participants, lower grip strength (OR = 1.25, p < 0.001) and high nutritional risk (OR = 2.24, p < 0.001) were associated with depression. For men, being in a relationship (OR = 0.62, p < 0.001), completing post-secondary education (OR = 0.82, p < 0.05), higher fat (ORs = 0.67–83, p’s < 0.05) and omega-3 egg intake (OR = 0.86, p < 0.05) as well as moderate intakes of fruits/vegetables and calcium/high vitamin D sources (ORs = 0.71–0.743, p’s < 0.05) predicted a lower likelihood of depression. For men, chronic conditions (ORs = 1.36–3.65, p’s < 0.001), chronic pain (OR = 1.86, p < 0.001), smoking (OR = 1.17, p < 0.001), or chocolate consumption (ORs = 1.14–1.72, p’s < 0.05) predicted a higher likelihood of depression. Conclusions: The odds of developing depression were highest among immigrant women. Depression in middle-aged and older adults is also associated with socioeconomic, physical, and nutritional factors and the relationships differ by sex. These results provide insights for mental health interventions specific to adults aged 45–85.
